I found this case of bad posterisation:
But, using another profile I got this:
Interestingly, Capture One 8.1 also causes banding, although used with their own profile for the the P45+ back
An profile I generated with a very old version of Anders Torger's DCamProf had none or very little issues:
The raw file is here: http://echophoto.dnsalias.net/ekr/Ar...7-CF046278.iiq
In this case, Adobe Standard Profile in Lightroom produced the best results. Capture One also produced banding artefacts. DCP profiles generated with Color Checker Passport software and Adobe DNG Profile Editor caused banding, but Adobe Standard Profile did not and nor did profiles generated by Anders Torger's DCamProf.
Just to say, the raw file is a 16-bit raw from a P45+ back.
Why I posted this on a Sony thread? Just to demonstrate that colour management can cause bad artefacts even on "real" 16 bit files.
